Embedding simply connected 2-complexes in 3-space -- I. A Kuratowski-type characterisation
Abstract
We characterise the embeddability of simply connected locally 3-connected 2-dimensional simplicial complexes in 3-space in a way analogous to Kuratowski's characterisation of graph planarity, by excluded minors. This answers questions of Lov\'asz, Pardon and Wagner.
